I've never been one to dog the post office for its service. In fact, I have always been quite happy with it. For an outfit with so many structural problems, it's quite efficient, at least when it comes to delivering the mail.

Anyhow, Amazon must have its name, image-wise, written all over this USPS-saving Sunday delivery initiative. The mail carrier appears more casual than the standard weekday and Saturday postal employees. This jibes with how Amazon does business, namely its Amazon Fresh grocery delivery service in the Seattle and Los Angeles areas.

I'll have a full treatment on why investors should be bullish AMZN headed into the holidays Monday morning on TheStreet. My thesis goes beyond Amazon's ongoing and obvious retail dominance, illustrated most recently by this move to further squash its lame brick-and-mortar based competition.
